Metrosideros plant named ‘Tahitian Sunset’

ABSTRACT

A new cultivar of  Metrosideros  plant named ‘Tahitian Sunset’ that is characterized by green and yellow variegated leaves, coral colored flowers and short internodes.

Botanical classification: Metrosideros collina.

Variety denomination: ‘Tahitian Sunset’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Metrosideros plant botanically known as Metrosideros collina and hereinafter referred to by the cultivar name ‘Tahitian Sunset’.

The cultivar ‘Tahitian Sunset’ was discovered as a naturally occurring branch mutation of Metrosideros collina ‘Tahiti’ (not patented). ‘Tahitian Sunset’ was discovered in 2004 in a cultivated area of Auckland, New Zealand.

Asexual reproduction of the new cultivar ‘Tahitian Sunset’ first occurred by softwood tip cuttings in 2004 in Auckland, New Zealand. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Metrosideros cultivar ‘Tahitian Sunset’. These traits in combination distinguish ‘Tahitian Sunset’ as a new and distinct cultivar apart from other existing known varieties of Metrosideros.

-   -   1. ‘Tahitian Sunset’ exhibits green and yellow variegated         leaves.     -   2. ‘Tahitian Sunset’ exhibits coral colored flowers.     -   3. ‘Tahitian Sunset’ exhibits short internodes.

The closest comparison cultivar is the parent plant Metrosideros ‘Tahiti’. ‘Tahitian Sunset’ is distinguishable from ‘Tahiti’ by the following characteristics:

-   -   1. ‘Tahitian Sunset’ exhibits green and yellow variegated         leaves. The leaves of ‘Tahiti’ are green.     -   2. ‘Tahitian Sunset’ exhibits a shorter internode length than         the internode length of ‘Tahiti’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographs illustrates the distinguishing traits of Metrosideros ‘Tahitian Sunset’.

The plant in the photograph of sheet 1 shows an overall view of a 1 year old plant.

The photograph of sheet 2 shows a close-up view of the flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Metrosideros cultivar named ‘Tahitian Sunset’. Data was collected in Auckland, New Zealand from 1 year old plants grown outdoors in 1.5 liter containers. The time of year was Spring in the Southern Hemisphere and the temperature range was 12–18 degrees Centigrade during the day and 4–11 degrees Centigrade at night. The light level was natural outdoor light. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Tahitian Sunset’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
